Understanding Shortwave Antennas - Basic of shortwave antennas

Smart Antennas Tutorial - Smart antennas or the adaptive antenna array and smart antenna technology used with SDR, cognitive radio, MIMO, and other new technologies.

Communications Towers - Basic information about tower purchasing and installation will help you to communicate your requirements to a tower manufacturer, leading to better decisions and a smoother process from inception to installation.

Discone antenna - About the basics of what is a discone antenna for wide band or bandwidth omnidirectional applications

Horn antenna - An overview of the basics of the horn antenna used in RF microwave applications.

Coffee Can WiFi Antenna - This wi-fi antenna design is a much simpler DIY project than the pringles cantenna. Basically there are 3 parts to a build-your-own 2.4 Ghz cantenna kit: a pigtail, an N-female connector and a metal coffee can.

Learning Morse Code by GW6ITJ - GW6ITJ articles on morse code, learning techniques, clubs and organizations and a custom learning software.

Morse Resource - Resources related to Morse Code and Amateur Radio

LearnMorseCode.info - How to learn Morse Code, a web site dedicate to morse code learning

Decoding multiple Morse code signals - Decoding multiple Morse code signals automatically on a noisy RF band

QRSS beacon - 30 meters beacon from UK. QRSS is a method of sending very slow morse code.

Morse Decoder - Morse Decoder decodes Morse code characters trough the built-in microphone of your Android device.

DroidRTTY - DroidRTTY is an Android app to decode and encode Ham Radio RTTY with the build in microphone/speaker or wired to your radio.

Navtex decoder - Frisnit Navtex decoder

Yand - Yet Another Navtex decoder is a windows NAVTEXT decoding software

APT Decoder - APTDecoder is a free software for recording and decoding signals transmitted by NOAA POES APT enabled weather satellites. It is run on a NT-based version of Window

MorseDec - MorseDec decodes and encodes Morse with a range of 5 to 50 wpm. It includes: auto-tracking for wpm speed, macros, spectrum analyzer. Easy to use but powerful.

OZ2M - Next generation beacon - Next Generation Beacon hardware platform encompasses both analog and digital modes, i.e. CW FSK and MGM in a mixed mode configuration. The advantage of the mixed mode is that humans can decode the CW FSK by ear and the MGM can be decoded by computers way below what is audible. Therefore the MGM can be used for “pre-human-conditions” or early warning monitoring.

QLF Filter - Microprocessor based interface designed receives a signal from a Morse key, processes it, and re-transmits it to the radio. A microprocessor in the circuit is pre-programmed with a proprietary algorithm which makes a number of measurements and adjustments to the less percise human generated code.
